Kind Code:
A1
Abstract:
Disclosed is a drainage adapter pipe fitting, comprising an adapter pipe body. The adapter pipe body has at least two water inlets and one water outlet, and the adapter pipe body is internally provided with at least two drainage channels connecting the water outlet and different water inlets. A check mechanism is mounted in at least one of the drainage channels. According to the drainage adapter pipe fitting provided by the present invention, the backflow of water may be prevented by means of mounting a check mechanism in at least one drainage channel. Moreover, an adapter pipe body has at least two drainage channels. When a plurality of drainage pipes respectively connected to a plurality of water inlets simultaneously drain water, the poor drainage of the drainage pipes due to the mutual influence of water flow can be avoided. When the plurality of drainage pipes respectively connected to the plurality of water inlets separately drain water, water may be prevented from flowing back into other drainage pipes.
